By now you’ve almost certainly received a letter like the one in this image from Google Analytics:
No, it’s not a scam. Yes, you really do have only a few weeks left.
What does this mean? It means you’ve got to be on the latest Analytics tracking code, which has no backwards compatibility to the old system, and if you haven’t updated to it yet, your stats tracking will break. This means anything you’re tracking in Adsense or Google Ads could possibly malfunction. Not that many people who are deeply interested in tracking their success online will have ignored the previous year’s worth of notifications, but you’re actally all the way out of time to change to the new system.
If you’re on WordPress, I recommend switching to the Google Site Kit plugin – it’s free, and it will help you switch to using just the correct analytics, and keep you connected to Google correctly.
If you want MWM to help you get this resolved correctly, send us an email asking for the Analytics set-up or debug service.
